| 摘 要： | 用燃烧法制备Pr~(3+)掺杂的SrAl_2O_4:Eu~(2+)、Dy~(3+)长余辉发光粉体,研究了Pr~(3+)掺杂对其发光性能的影响。结果表明,合成的单相SrAl_2O_4样品具有单斜晶系结构,荧光发射光谱是连续宽带谱,峰位于515 nm,激发光谱是峰值在320 nm和360 nm的连续宽带谱。掺杂Pr~(3+)对形成晶粒尺寸均匀的固溶体有一定的促进作用,使其余辉初始亮度为不掺杂时的3倍。

| Abstract: | Pr~(3+) doped SrAl_2O_4:Eu~(2+),Dy~(3+) phosphor was synthesized by combustion method. The modification of optical properties of the sample has been investigated.X-ray diffraction pattern indicates that the samples possess a monoclinic crystal structure.The emission spectra shows a continuous luminescence band with a peak at 515nm and excitation spectra shows two peaks at 320 and 360 nm.The decay curves show that the initial intensity is three times before doping praseodymium.The morphology shows praseodymi... |
